If you haven’t been on the Steam store page recently you may have missed that the famous Potato Sack Bundle is on sale again! Last time we saw The Potato Sack it was a lead up to the hugely popular Portal 2, which ended up releasing a couple of hours earlier than expected thanks to the bundle. There is no mysterious update this time around although there are rumors saying that the potato achievements are back. Could Valve be up to something? Or is this just another summer bundle sale?
